Step 10: Draw a Bead
After tacking, remove any clamps.
Start a weld pool by jamming down the pedal fast to form a weld pool.
Then lighten up on the pedal, to regulate the current.
If the metal starts to burn/melt away, too much current is being dumped in, back off the foot pedal.
If the metal gets a flaky, but not liquid look to it, put more power in (step on the pedal harder).
To weld aluminum, move the electrode towards the rod, while feeding rod into the pool. The rod should be to the side of the tungsten electrode that the weld will form or grow towards. This is known as "leading" the electrode.
To weld steel, the electrode travels first down the weld line, and the rod chases after, "following" the heat.
